v7.1.1

1f3a539

Calcpad VM 7.1.1

What's new in this version:

Added more examples: Combinatorics.cpd, Mandelbrot Set.cpd, Solution of a triangle.cpd, Free Vibrations of Steel Pole.cpd.
Fixed converting to dimensionless units #376.
Fixed marking ‱ symbol as error #376.
Added new C-style shortcuts for non-standard symbols:
&& for ∧ (AND) and || for ∨ (OR).
The other shortcuts from old versions, you can use are as follows:
%% -> ⦼ (modulo)
== -> ≡ (equal to)
!= -> ≠ (not equal to)
<= -> ≤ (less than or equal to)

= -> ≥ (greater than or equal to)
Symbol ‱ added to uppercase Greek letters strip bellow the code textbox at the place of ‰.
Fixed minor rounding bug.

v7.0.9

961c5ba

Calcpad VM 7.0.9

What's new in this version:

New functions msolve and cmsolve were added for solving the generalized matrix equation AX = B, where X and B are matrices.
Fixed bug with find_le, mfind_le, find_le and mfind_le for comparing unexact values.
FIxed indexes in loops, issue #367.

The new functions msolve and cmsolve can be used to solve efficiently FEM problems with multiple load cases. Assume we have a global stiffness matrix K and global load vectors F_k for k = 1 to nl (number of load cases). Previously, you had to call Z_k = clsolve(K, F_k) nl times (for each load case k).

Now, you can join preliminary all load vectors F_k into a single matrix F as columns. Then, you can call Z = cmsolve(K, F) just once. The columns of the resulting matrix Z will contain the displacement vectors for the correspoinding load cases.

The second option is several time faster because the decomposition of K is performed only once in the beginning and backsubstitutions for different load cases are executed after that in parallel.
